Application filed September 9, 1927. Serial No. 218,489.

This inventionrelates to eonveyers for an neal ng furnaces and more particularly to a feeding device and a metal sheetseparating device by means of which the so-called good them as they emerge from the furnace, thereby saving a great deal of labor.

The invention is illustrated in the accompanying drawing in which Figure 1 is a fragmentary view partly in section of the rear part of the furnace and. the plate feeding rolls; Fig. 2 is a a-rspectivc view of a portion of the front of the furnace with the sheet separating tables and the high and low speed rolls. Fig. 3 is a diagram showing the method of placing the goodplates (sheets) on the bad ones.

Referring to Fig. l, 1 represents the outer wall of the furnace, 2 is a structural steel frame imbedded in said wall and extending through the furnace, both front and rear carrying the various rollers and their brackets. 3 are steel conveyer rollers carried by frame 2 and run the length of the furnace. 4 are the feed rollers supported hybracket 5 attached to frame 2. t3, 7 and 8 are sloping planes that act as guides for feeding the plates into the furnace. 9 represents a good -.plate and 10 represents a had .plate being fed into the furnace and it. will be noted that the bad plate is half ,way through the roll before the good plate is fed in. 'lhis'results in an arrangement of plates as shown in diagram of Fig. 3.

By way of explanation it may be Well to state that in running a plate. or sheet. thin the annealing furnace it i customary to use a bad plate on which the plate to he annealed rests, the had plate providing a sort of protection to tlu' 'oo l plate while it passes thru the furna e.

Referring now to Fig. 2. the plates emerging from the furnace are caught by the slow speed set of rollers ll and from them are fed into a second set of l'OllQIS 12, which rotate at; a considerably greater speed. The difference of the speed of thetwo sets of rollers causes the plate in the fast set of rollers to travel faster than the plate in the low speed set. thus separating them and causing a single plate to fall at one time on the horizontal table. Ob-

viously the distance between the set of rollers is slightly greater than the length of one plate.

time raising table 17 to a horizontal position.

lly this time the good plate has reached the fast set of rollers and is'fed forward onto table 17 where its weight; causes the table to tip sideways sliding the good plate off onto its pile at side of apparatus.

Table 17 is hinged to support 18 at point 19 and is connected to the upper table 13 by means of cable 20 through a ball joint at its lower end. Table 13 has attached to its lower -side brackets carrying rod 22 on which balancin'g weight 23 slides. Weight 23 may be fastehed at any point by set screw 24.

A small roller 28 carried at the front of table lll. aids in feeding plates onto table 17 when table 13 is tilted. I claim:

1. A sheet separating apparatus for furnaces comprising a conveyor adapted to convey upper and lower sheets thereon in overlying relation, and means at the outlet end of the conveyor to separate and discharge the upper and lower sheets respectively to different places said means comprising a pair of receiving devices movable to alternately register the same with the end of the con vcycr.

2. An apparatus as set forth in claim 1, the said means comprising an upper tilting table to receive the upper sheets and a lower tilting table to receive the lower sheets in alternation.

3. The combination with a conveyer adaptcd to carry upper and lower sheets in overlamad-relation along the same. of an upper tilting table at the discharge end of the conveyor, adapted to receive the lower sheets, and a lower tilting table at sa 'l end. 0peratively connected to the upper table and adapt ed to receive the upper sheets. said table being movable to alternately register their ends with the discharge end of the conveyor.

4:. The combination with a conveyer adapted to convey superposed overlapping plates,

of means to separate the upper and lower 7 plates as they are discharged from the con-.

Veycr and to deliver them to dill'erent places, said mez ns comprising a pair of separating and delivering devices movable to'alternately register the same with the discharge end 'of theeonreyer. V

5. The combination with a eonreyer :ulnpted to ('onvey upper and lower phitez-in over.-

l apped relation, of meme; 'to separate the blates as tht) are disclnug 'd from the conveyer, comprising upper :iml im tilting tables operqblc to alternately register with the end of the conveyer.

6. The. (omhin'utionstated in eluim 5,1rm: vttljblc tiltm; lengthwise 'us'to the eunreyer eom])ri.\'in; separate feed rolls at; (litl'erent? heights and guides associated with the respective rolls. c

In testimony whereof, I- do allix my signature.
